I think my Lilli is done.

This is the best draw test I could do after trying 4 point calibrations, 25 point calibrations, changed drivers, uninstalled, re-installed, etc. Notice the completely wanky vertical line on the far right. That was when I ran the stylus down the farthest right edge.

I think my overlay is just screwed up. I've searched but is there anything else anyone can think of that might be causing this? If not I have three options, what would you recommend?

1.Buy a new overlay and hope it works.
2.Buy a whole new Lilliput
3.Buy a Xenarc (but I'd have to totally re-do my fabrication of my dash. Last time it took me several months here and there to do it since I'm so busy)
